Tuning idle speed circuit

>Checking for voltage on the plug that connects to the Idle Speed 
Motor is a good start, but it's not everything that you need to do.<

Yes, quite true. But I must point out that there will *always" be 12 
vdc on that one pin to the idle motor, even it the ECU is not 
working. Checking for power there is pretty usless, especially if you 
reference it to another ground.

This is because the ECU sinks current to the motor, it switches the 
two grounds. The plus side is wired directly to the motor internally 
through the ECU, checking for it is of only minor importance. Or just 
do what those who can't repair it say: Yank the idle system 
completely off and make the car "better" than it was designed to be ;)
